Life on Mars

Here’s what I don’t get. Why is everyone hung up on whether there is life on Mars, and on the related question of whether that planet ever had water? There are other bodies in our solar system that have water-ice crusts, and may have water beneath these crusts held in liquid state by heat from geological activity. Some such bodies are Europa, a moon of Jupiter, and Triton, a moon of Neptune. On earth, we have some sections of our oceans heated by volcanic activity and supporting an ecosystem completely independent of the rest of life on our planet. If this can happen here, perhaps it can happen in the sub-surface oceans of one of these moons.

But we’re still hung up on Mars. Why, because he’s closer? Forget him. He’s not putting out. It’s time to stop sending space-probes by his house to see if he’s home. Move on, and get with a satellite that has some potential.
